ISSUE-174: potential conflict between Link: and <link> semantics

potential conflict between Link: and <link> semantics

The decision on ISSUE-27 has resulted in a state where the semantics of link relations may depend on where they appear in (Link: HTTP header vs HTML content).

Minimally, the spec should clarify that there's potential for conflict, and explain that the semantics of link relations appearing in the HTTP Link header field are defined by RFC 5988 and the IANA link relations registry, not the Microformats Wiki.
